More Than 50 Killed in Las Vegas Concert Shooting, Deadliest in U.S. History

A lone gunman shooting from a hotel room in Las Vegas' Mandalay Bay killed more than 50 concert-goers and injured more than 400 Sunday night (October 1) in what has since been deemed the deadliest domestic attack in modern United States history.

According to The New York Times, a crowd of thousands at Route 91 Harvest Festival, a three-day country music event, was sent into panic sometime after 10 PM, when the gunman opened fire onto the crowds while Jason Aldean performed. Police said the suspect was dead when they found him in his rotel room, but say there was "a companion" that they are "confident" they've found.

The suspect was said to have upwards of 10 rifles at his disposal.

Aldean wrote in an Instagram post that the night was nothing short of a nightmare.

“Tonight has been beyond horrific. I still don't know what to say but wanted to let everyone know that Me and my Crew are safe,” he noted.
